re PR middle-end/71581 (ICE on valid code on x86_64-linux-gnu with -Wuninitialized (Segmentation fault))

PR middle-end/71581
* tree-ssa-uninit.c (warn_uninit): If EXPR and VAR are NULL,
see if T isn't anonymous SSA_NAME with COMPLEX_EXPR created
for conversion of scalar user var to complex type and use the
underlying SSA_NAME_VAR in that case.  If EXPR is still NULL,
punt.

* gcc.dg/pr71581.c: New test.
